Pilley's 

 Combination 

 Flue Brush and 

 Scraper 



By simply turning the rod or handle, 

 the ends contract until it will readily pass 

 into the flue. Then by turning the handle 

 in an opposite direction the cleaner is 

 gradually expanded until it fits the tube 

 perfectly; the brush following leaves the 

 tube absolutely clean.

that the hot water will run into the 

 pump by gravity, as no pump will lift 

 hot water. The plant in which I am 

 engineer is in a range of greenhouses 

 containing 92,000 square feet of glass. 

 We carry forty pounds on the boiler 

 and ten pounds on the heating system, 

 by means of a reducing valve. Before 

 we put in the reducing valve, pump, 

 receiver and steam traps, the conden- 

 sation was returned by gravity and the 

 temperature of the return water was 

 from 120 to 180 degrees; now the con- 

 densation comes back to the pump with 

 a temperature of 200 to 210 degrees, 

 which means a big saving in coal

TWO REASONS FOR TROUBLE. 



We have two greenhouses, each 16x60 

 and ten feet to the ridge, with twenty 

 inches of side glass and concrete walls, 

 three feet high. Each house -is piped 

 as follows: One 3-inch main, rising 

 from the boiler about five feet, then 

 pitching down to the farther end of the 

 greenhouse and there dropping into 

 fifteen 1^4-inch returns under the 

 benches, and one 1%-inch return along 

 the side glass. The expansion tank is 

 connected to both 3-inch mains at the 

 highest point in the boiler shed. The 

 boiler is cast-iron, a good make and 

 rated at 1,250 feet of radiation. It has 

 a grate 20x30 inches. The boiler room 

 floor is about one foot lower than the 

 paths of the greenhouses. We are not 

 getting satisfactory results and we 

 have to keep the boiler going at full 

 force to get 60 degrees in moderately 

 cold weather. In zero weather we can- 

 not get a higher temperature than 40 

 degrees. We shall be pleased to get 

 some advice through your columns. We 

 are located in southwestern Michigan.

From the description given, it would 

 appear that at least two conditions 

 have combined to cause the trouble. It 

 is never advisable to use anything less 

 than 1^-inch pipe, and 2-inch pipe is 

 even better, unless the returns are five 

 to eight feet above the top of the 

 heater. The other contributing cause
